Fix common misspellings in text files. It's designed primarily for checking
misspelled words in source code, but it can be used with other files as well.

Python 2.7 or above.
You can use ``pip`` to install codespell with e.g.::
pip install codespell
**Note:** that upon installation with "make install" we don't have the "py" suffix.
For more in depth info please check usage with ``codespell -h``.
Some noteworthy flags::
codespell -w, --write-changes
The -w flag will actually implement the changes recommended by codespell. Not running with ``-w`` flag is the same as with doing a dry run. It is recommended to run this with the ``-i`` or ``--interactive`` flag.::
codespell -S, --skip=
Comma-separated list of files to skip. It accepts globs as well. Examples:
* to skip .eps & .txt files, invoke ``codespell --skip="*.eps,*.txt"``
* to skip directories, invoke ``codespell --skip="./src/3rd-Party,./src/Test"`` ::
codespell -I FILE, --ignore-words=FILE
This flag can be used to whitelist certain words that are in the ``codespell_lib/data/dictionary.txt``. The format of the whitelist file is one word per line. Invoke using: ``codespell -I path/to/file.txt`` to execute codespell referencing said whitelist. **Important note:** The whitelist passed to ``-I`` is case-sensitive based on how it is listed in ``dictionary.txt``.
Useful commands::
codespell -d -q 3 --skip="*.po,*.ts,./src/3rdParty,./src/Test"
List all typos found except translation files and some directories. Display them without terminal colors and with a quiet level of 3. ::
codespell -i 3 -w
Run interactive mode level 3 and write changes to file.
We ship a dictionary that is an improved version of the one available
`on Wikipedia <>`_
after applying them in projects like Linux Kernel, EFL, oFono among others.
You can provide your own version of the dictionary, but patches for
new/different entries are very welcome.
Dictionary format
The format of the dictionary was influenced by the one it originally came from,
i.e. from Wikipedia. The difference is how multiple options are treated and
that the last argument is the reason why a certain entry could not be applied
directly, but instead be manually inspected. E.g.:
1. Simple entry: one wrong word / one suggestion::
2. Entry with more than one suggested fix::
fiel->feel, field, file, phial,
Note the last comma! You need to use it, otherwise the last suggestion
will be discarded (see below for why). When there is more than one
suggestion, an automatic fix is not possible and the best we can do is
to give the user the file and line where the error occurred as well as
the suggestions.
3. Entry with one word, but with automatically fix disabled::
clas->class, disabled because of name clash in c++
Note that there isn't a comma in the end of the line. The last argument is
treated as the reason why a suggestion cannot be automatically applied.
To stay current with codespell developments it is possible to build codespell from GitHub via::
pip install --upgrade git+
**Important Notes:**
* Sometimes installing via ``pip`` will complain about permissions. If this is the case then run with ::
pip install --user --upgrade git+
* It has been reported that after installing from ``pip``, codespell can't be located. Please check the $PATH variable to see if ``~/.local/bin`` is present. If it isn't then add it to your path.
* If you decide to install via ``pip`` then be sure to remove any previously installed versions of codespell (via you OSs preferred app mananger).
